govardhane dhrte saile
asarad raksite vraje
go-lokad avrajat krsnam
surabhih sakra eva ca
Sukadeva Gosvami said: After Krsna had lifted Govardhana Hill and thus protected the inhabitants of Vraja from the terrible rainfall, Surabhi, the mother of the cows, came from her planet to see Krsna. She was accompanied by Indra.
The word go-lokat here indicates the material planet called Goloka which is filled with exceptional cows. Surabhi went joyfully to see Lord Krsna, but Indra went fearfully. As indicated by this verse, Lord Krsna had to adopt extraordinary measures to protect His Vrndavana associates from Indra’s obnoxious and offensive attack. Certainly Indra was ashamed, and also nervous about his future. Having acted improperly, he had fearfully gone to seek the shelter of Lord Brahma, who then ordered him to take along Surabhi from the material Goloka planet and go to see Krsna.
